Is it possible for hackers to give a fake IP address when visiting a website running PHP? I want to allow certain IP addresses have access to a website (other IP addresses not), is it possible for someone (e.g. hacker) to give fake IP address? If so, how is the website returned to this someone? If you have any reference or links on this, please send me!
